Specification forming part of Letters Patent No. 39,871. dated September 15, 1363.

T 0 all whom it may concern Be it known that I, FREDERICK ALDRICH, J r., of Augusta, in the county of Kalamazoo and State of Michigan, have invented a new and Improved Fruit-Ladder; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in which Figure 1 represents a side elevation of my Fig. 2 is a front elevation of the same.

Similar letters of reference in both figures indicate corresponding parts.

This invention consists in the arrangement of a platform secured to arms which are con nected by a pivot to the sides of the ladder, and by a second pivot to thesides of the support, in combination'with adjustable braces, in such a manner thatthe platform can be adjusted in a level position independent of the formation of the ground on which the ladder stands and of the height at which the same is to be placed. I

To enable those skilled in the art to make and use my invention, I will proceed to describe it.

A represents a ladder constructed with ver tical or longitudinal sides a and horizontal steps or rounds I), in the ordinary manner. To the upper ends of the sides a two arms, B, are attached by means of a pivot or pivots, 0, so that the same can readily swing up and down on the same, and those ends of the arms 13 opposite the pivot c are secured by a pivot, d, to the upper ends of the sides 6 of the support 0. This support is constructed similar to a ladder, with the sides 0 and transverse bars or rounds f, and the sides of the ladder and of the support are provided at their bottom ends with metal feet g, intended to catch in the ground and prevent the ladder from slipping. The arms B support the platform B, which is firmly secured to their upper edges, and by adjusting the support in relation to the ladder the platform can be brought in a horizontal position, no matter whether the ground on which the ladder stands be level or not. The arms B, which support the platform, will turn on the pivots 0 cl, and'they will readily adjust themselves to any position into which the ladder and support may be brought. The ladder is held in the desired position by braces D, which are hinged to the ends of the arms B next to the support, and which are secured to the sides of the ladder A by pins h, passing through holes in the sides of the ladder and in the braces. Each of the braces is provided with a series of holes, to allow of adjusting the same according to the desired position of the ladder in relation to the support.

When the ladder is not used, the platform can be turned up in line with the sides of the support, and the arms and ladder folded in between said sides. thereby bringing the whole device into a small compass, so that it can be FREDERICK ALD RICH, JR.
